If you have ever tried searching for maps in the Community Atlas, you might have noticed that there is an option for searching for text in the map. This option searches for text in the visible labels on the map itself, but also for text in the attached map notes. Since map notes are included in the search, it means that you can search for something like “Symbol Set 6” and get a list of all maps in the atlas that uses resources from SS6 (If you have looked at atlas maps, you may have noticed they all have a map note listing which products are required, which is why you can then search for this).
So, the interesting question here is how is this possible in the first place? FCW files are binary files after all, and not easily parsed by web server software, and the search would also be slow if it had to look through 1300+ files every time someone tried to search.
The solution here lies in a feature in CC3+ that can create a search index for a whole folder of maps. This feature was originally intended to use with the built in search feature in Campaign Cartographer, but as I’ve already reveled here, it can also be utilized by other tools, in this case my web server software to allow map searches despite the fact that the maps on the web server are just plain non-searchable images.
